3333----11115555 Starting the EngineStarting the EngineStarting the EngineStarting the Engine

(1) Refill the engine oil to factory spec.

(2) Check all the hoses and wires connection, then reconnect the negative side of the battery.

(4) Remove the ECM fuse and crank the engine to get oil pressure to the turbo. (Until the oil light

on the dash turns off) Check for any oil leaks, then reinstall the fuse and start the engine.

(5) While idling, check for any oil, coolant, or air leaks.

(6) After inspection, reinstall the under cover and other stock parts that were removed.

(7) On the initial run, be sure to have a boost gauge to check the turbo-actuator setting. This turbo

kit is preset to boost between 0.3kg/cm2 to 0.4kg/cm2.

It is very important that you monitor the boost pressure, and make sure not to over boost. Over

boosting can cause engine damage.

This completes the Turbo Kit installation.
